VISE.

SPECIFICATION forming part of Letters Patent No. 227,582, dated May 11,1880.

Application filed January 29, 1880. Patented in England November 21,1877. 1

To all whom t't may concern:

Be it known that I, WILSON RILEY, a subject of the Queen of GreatBritain and Ireland, and a resident of Keighley, in the county of York,England, have invented an Improved Parallel Vise,for which BritishLetters PatentNo. 4,372, dated November 21, 1877, were granted to me,and of which the following is a specification.

My invention relates to that class of parallel vises in which themovable jaw can be freely slid toward or from the fixed jaw to quicklyadjust it to any size of material to be held and then secured afteradjustment.

The object of my invention is so to construct a vise of this characterthat when the mova ble jaw is secured after adjustment it shall by thesame movement be drawn toward the fixed jaw, and the gripe on thematerial thereby be tightened.

In the accompanying drawings, Figure l is a longitudinal section of myimproved parallel vise; Fig. 2, a transverse section on the line 12,Fig. l, and Fig. 3 a perspective view of the vise with the movable partsdetached.

The bed-plate X of the vise may be secured to the bench by a bolt orbolts, or by any other suitable means, and to this bed-plate is boltedor otherwise attached the cap-piece O, carrying the fixed jaw K. Theupper face of the bed-plate and the under side of the cap are groovedlongitudinally, as indicated at D in Fig. 2, for the reception of theslotted bar B, which carries the movable jaw A, and which can slide onways in the said groove in the bed-plate and cap-pieoe.

To bearings b b, in the opposite ends of the slotted bar B, is adapted aspindle, F, to which is secured, at the front outer end, a handlever,Gr, Figs. 1 and 3. This spindle F carries near its opposite end, withinthe slotted bar B, a scroll-cam, H. On this cam rests'a block, L, whichhas flanges embracing said cam,- as indicated in Fig. 1, and which isguided in a longitudinal groove, J, on the cap 5 piece 0. The uppersurface of this block is provided with a series of teeth, which areadapted to fit into corresponding teeth on the under side of alongitudinal plate, E, secured to or forming part of the cap-piece 0.

By manipulating the hand-lever G the spindle F with its cam H can becaused to move the block L into or out of contact with the toothed plateE. When the block is not in contact with the plate E the bar carryingthe movable jaw A can be slid in the grooved bedplate and cap-piece tothe required position to hold the material to be operated on, when, byturning the handle G in the direction of the arrow, Fig. 3, the cam Hwill raise the toothed block L into contact with the toothed plate E,and,owing to the spiral or scroll shape of the cam, will draw the bar Band the jaw A closer to the jaw K, and consequently secure the materialfirmly between the jaws.

In order to limit the throw of the handle G,

and consequent movement of the spindle F, stops as are formed on the endof the bar B, a shoulder, g, on handle 'comin g into contact with one orother of these stops, according to the position to which the handle ismoved.

I claim as my invention- In a parallel vise, the combination of thefixed cap-piece carrying the fixed jaw and toothed plate E with the barcarrying the movable jaw and spindle F, provided with a handle and aspiral or scroll cam, H, and movable toothed block L, all substantiallyas and for the purpose described.

In witness whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
